How do you know whether a system of equations has no solution, one solution, ormany solutions?

How can you identify whether a system is consistent or inconsistent????

Please Help me!!!!
Thanks so much!

I believe it is consistant if there is onlii one variable well i mean like the onliy thing that can be multplied by 7 is 7 something like that. i hoped that helped
